Abstract: A method, computer-readable medium, and system for providing direct transaction access to information residing on a host system. The system includes a transaction server that routes transactions between the host system and a client device. The transaction server maps client transactions to host transactions using direct transaction access that allows the transaction server to bypass the displays of the host system and to obtain information directly from the host source. Each client transaction is mapped to one or more host transactions. Each host transaction includes inputs and outputs. The host inputs are resolved to addressable references before run-time. The transaction server processes the client transactions concurrently. A graphical user interface is provided that allows a user to create client transactions without writing any programming code. The computer readable-media is loaded on the transaction server without requiring additional software on the host system.
